Check out the topic "Google 3D Warehouse for commercial game?" -- particularly the response from monalaw (who is actually a lawyer) -- and the topic "Google 3D Warehouse and copyright".

It would appear that you are free to use the content commercially. It's probably a good idea to credit the original authors, but doing so may or may not actually be necessary.
